The Future of the Internal Combustion Engine: Camless

[CRG Racer24]

That is incredible.. both that and the Michigan State technology. I'm all for this.. I **** electric cars.

[Average_Jerk]

I read the title as "features of the internal combustion engine". then saw the first line explaining how it was new. turns out thats not what the title really says at all

Absolutely astounding technology, I really hope this makes as big of an impact as it should.

However...

I will never, ever want sounds like this to go away.

gahhhh, Cam sounds like that never get old.

Why would it go away? The air valves are controlled by electronics so the coding can be programmed in for that. you could have infinately variable valvetrain profiles. at the press of a button.

What he said though. Would be so easy to adjust tuning. (In theory anyways.)

Say you had a stock n/a motor and you wanted to turbo it. As long as the bottom end is strong enough and the heads flow well enough, all you'd need to do is add bigger injectors and adjust the valve timing. Obviously that's not all but you get the point. Instead of having to replace other parts it could all be done through tuning software.

And another thing, not having to deal with cam/crank timing or timing belts/chains in general. Oh I like the sounds of that.

no more timing chains and no more timing belts...that prevents engine trouble and means less maintenance costs...

I'm guessing higher redline and better response as well. just from less rotating mass.

[SuperMegaDeathRay]

this is like finding the amber room...nothing negative to it...except increased production costs...

[SheaMoose]

I was just thinking about this today O.o
I'm pretty stoked to see that someone is actually developing it.

[SuperMegaDeathRay]

i read something similar in an internal magazine which ford dealers receive in 2011...i didn't think about it ever since...

[Moose]

Super super cool stuff.

[Jesus Christ]

Thank god this is actually good for performance, unlike that direct injection BS. This technology isn't new but it's cool someone is actually putting in the time to develop it for production. I'm not 100% but i'm pretty sure that F1 used pneumatic valves for a good while. Also like Z mentioned camless motor cycle engines in 2007 but even before that ducati ran camless motors.

I heard of this from an engine builder who was actually trying to retro fit a similar system in a traditional cammed engine. He claimed that you can take the engine to the mid 20K rpms without any valve float or bounce that high revving engines are more prone to having.

On paper, it sounds good but don't be so quick to call it a god send though. It HAS to be louder than hell, it WILL be nightmare when the tiniest seals go out, it will be a nightmare when the pump goes out, plumbing and air leaks will be a nightmare. You know they wont mount that pump on anywhere but inside the head so to check the pump or service anything, you guessed it, head has to come off. With so many variables on such a vital component, it brings to mind the wankel. That shit on paper sounds like jesus himself engineered it, but in reality its...not good to keep it PC. It all comes down to execution i guess, can't say i trust the swedes to get this right.

So fucking badass!
